Inversion formula of multifractal energy dissipation in 3D fully developed turbulence [PDF]

open access: yes, 2006
The concept of inverse statistics in turbulence has attracted much attention in the recent years. It is argued that the scaling exponents of the direct structure functions and the inverse structure functions satisfy an inversion formula. This proposition

Optimized numerical inverse Laplace transformation

open access: yesACM SIGMETRICS Performance Evaluation Review, 2022
Among the numerical inverse Laplace transformation (NILT) methods, those that belong to the Abate-Whitt framework (AWF) are considered to be the most efficient ones currently. It is a characteristic feature of the AWF NILT procedures that they are independent of the transform function and the time point of interest. In this work we propose an

Run up flow of a couple stress fluid between parallel plates

open access: yesNonlinear Analysis, 2010
Consider the flow of an incompressible fluid between two parallel plates, initially induced by a constant pressure gradient. After steady state is attained, the pressure gradient is suddenly with drawn while the plates are impulsively started ...

Solving the time-dependent Schr\"odinger equation with absorbing boundary conditions and source terms in Mathematica 6.0

open access: yes, 2010
In recent decades a lot of research has been done on the numerical solution of the time-dependent Schr\"odinger equation. On the one hand, some of the proposed numerical methods do not need any kind of matrix inversion, but source terms cannot be easily ...

A Numerical Method for Inverse Spectral Problems

open access: yesBulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2015
На основе метода Галеркина разработан новый численный метод решения обратных спектральных задач, порожденных дискретными полуограниченными снизу операторами. В отличии от метода решения обратных спектральных задач, основанного на теории регуляризованных следов дискретных полуограниченными снизу операторов, в разработанном методе ослаблены ограничения ...

Research on Optimization of Roadway Support Based on Parameterized Numerical Calculation Inversion Analysis

open access: yesMeikuang Anquan, 2020
A roadway support optimization method based on parametric numerical calculation inversion analysis is proposed. Based on the measured values, the geomechanical parameters with less error between the calculated results and the actual mineralization are ...

Generalized Post-Widder inversion formula with application to statistics [PDF]

open access: yes, 2015
In this work we derive an inversion formula for the Laplace transform of a density observed on a curve in the complex domain, which generalizes the well known Post-Widder formula.

Analysis of Volterra Integrodifferential Equations with the Fractal-Fractional Differential Operator

open access: yesComplexity, 2023
In this paper, a class of integrodifferential equations with the Caputo fractal-fractional derivative is considered. We study the exact and numerical solutions of the said problem with a fractal-fractional differential operator.

Lossy transmission line response via numerical Laplace transform inversion [PDF]

open access: yes, 1994
An efficient transient analysis of lossy lines with nonlinear loads requires the ability to compute and represent a suitable set of line impulse responses.

Sparse inversion of Stokes profiles. I. Two-dimensional Milne-Eddington inversions

open access: yes, 2015
Inversion codes are numerical tools used for the inference of physical properties from the observations. Despite their success, the quality of current spectropolarimetric observations and those expected in the near future presents a challenge to current ...
